ldyte1 Posted October 3, 2018 Author Share Posted October 3, 2018 (edited) Sorry for the long time to attach the video, here it is. After i throttle and then back off it has a high pitched pinging noise? What is that and what causes it? Also the fix?

debo Posted January 5, 2019 Share Posted January 5, 2019 With all the symptoms you are having it is the same as my macstar 28 the problem with mine is loss of compression especially when hot due to a score mark on my piston I’m just bashing it until it blows then I will upgrade it ?

Hmm, it certainly is a pain in the arse engine. Just started up today, first start in about 2 or so months. There now seems to be a leak/fuel common from the top of the head. Think im just going to do the same as you haha, bash it till it dies, not worth anything on ebay is it? Also what engine do you plan to get next, i really need ideas i have no clue what engines are good to buy?! Quote Link to comment Share on other sites More sharing options...

Off topic but I never changed the plug on my Savage 21 that was used daily from when I bought it new when they came out to when I changed the engine in 2013 lol.

Marchew Posted September 9, 2019 Share Posted September 9, 2019 I have this engine it is a nightmare, the pinging you hear before it settles is the high speed to lean, once the throttle closes it takes time for the low speed to kick in as the fuel in the crack case needs to clear out, think your low speed is too rich. Set the idle gap to about 1mm or a bit less, 0.8mm, let the engine idle for ten second and boot it to full throttle, if plumes of smoke comes out and the car struggles to pull away it too rich. I find there’s a fine line for the high speed, a tad too lean and it won’t settle to idle right, tad too rich and there’s no performance. Also check of air leeks, crack seal, carb seal, needle seals, fuel tank seals, all can cause issues. Quote Link to comment Share on other sites More sharing options...
